Forced "SWAP"="RAW" code preventing snapshots and backups

We are trying to create snapshots in our cluster (shared ceph-fs on all nodes), but this is only possible if all devices are QCOW2.
Problem is, we use SWAP devices, which - no matter what you select in the UI, can only be RAW because of that code in /usr/lib/one/sh/scripts_common.sh:
…
function mkfs_command {
DST=$1
FSTYPE=2 SIZE={3:-0}

    if [ "$FSTYPE" = "qcow2" ]; then
        QEMU_FORMAT="qcow2"
    else
        QEMU_FORMAT="raw"
    fi

    echo "$QEMU_IMG create -f ${QEMU_FORMAT} ${DST} ${SIZE}M"

    if [ "$FSTYPE" = "swap" ]; then
        echo "$MKSWAP -L swap $DST"
    fi
}

…
And because the mkswap script is hardcoded to FSTYPE=swap, you will never be able to create snapshots as soon as you add a swap device.
Is there a reason for that?
